When sourcing Automotive PU Sealant, the key question is not simply which product to buy, but which product fits each sealing application. Windshield sealing and body panel sealing involve different substrates, joint conditions, and application requirements.
For distributors, contractors, and procurement teams, a clear product structure makes sourcing easier and helps avoid using the wrong sealant across applications. Victor Sealant TP702 is designed for windshield sealing, while TP703 is developed for automotive body panels and body joints. Together, they provide a practical product range for automotive sealing programs and bulk supply.
TP702 for Windshield Applications: PU Sealant Selection and Application Requirements
Victor Sealant TP702 Polyurethane Sealant for Windshield is presented as a one-component, moisture-curing, non-sag, fast-cure polyurethane sealant for windshields. The published product page lists black colour and 310 ml or 600 ml packaging. It is positioned for windshield-related work, but the final recommendation still needs to be checked against the exact glass, frame, coating, primer, bead geometry, and installation process.
The public TP702 Windshield Polyurethane Sealant reference data lists a tack-free time of 30–90 minutes, curing speed of 3–5mm/24 h, solid content of at least 95%, extrudability of at least 80g/min, hardness of 60 Shore A, density of 1.3 g/cm³, tensile strength of at least 5.0 MPa, elongation at break of at least 400%, tear strength of at least 12 MPa and shear strength of at least 4.5 N/mm.
These figures are useful for technical screening, not a replacement for the current TDS. The buyer should request test methods, conditions, tolerances, storage information, and application instructions before using them in a project submittal or customer quotation.
For a distributor or automotive engineering contractor, the TP702 review should include:
- the windshield glass construction and surface treatment;
- the frame material and primer or lacquer system;
- cleaning and priming requirements;
- cartridge, sausage-pack or pump compatibility;
- bead size, non-sag behaviour and tooling process;
- tack-free time, cure rate and release schedule;
- packaging, shelf life, MOQ and repeat-order capacity.
TP702 moisture-curing windshield sealant should therefore be presented as the windshield product in the Tengyu automotive sealant range, not as a general replacement for body seam sealants.
TP703 for Automotive Body Sealing: Product Selection for Panel and Seam Applications
Victor Sealant TP703 automotive body panel sealant is presented as a single-component polyurethane automotive sealant for car body metal bonding. After curing, it provides a permanently elastic bond. The official product page positions TP703 for automotive body panel sealing and lists water resistance, ageing resistance, softness, and bonding performance among its characteristics.
The listed applications include sealing weld joints of autos and machinery, sealing joints of containers and shelters, sealing and waterproofing joints of van vehicles, sealing bus air-conditioning installations, and bonding automotive metal plates. The product page lists 310 ml and 600 ml packaging and black colour.
The public TP703 technical data lists paste appearance, specific gravity of 1.3 kg/L, sagging below 3 mm, surface dry time below 60 minutes, curing rate of 3 mm/24 h, Shore A hardness of 40, tensile strength of 2.0 MPa, elongation at break above400%, tear strength of 11 N/mm, service temperature of -40°C to +80°C, and short-time application up to 120°C for at most 8 hours. These published values must be checked against the latest approved TDS before formal approval.
TP703 automotive body seam polyurethane sealant should be evaluated against the body-sealing process rather than against windshield requirements. The buyer should confirm:
- whether the joint is a weld seam, body panel connection, van joint or equipment installation;
- whether the surface is bare metal, painted metal, coated steel or aluminium;
- whether the cured sealant must be painted or remain exposed;
- whether the bead requires non-sag behaviour on vertical or overhead joints;
- whether the project needs water resistance, elasticity, abrasion resistance or tear resistance;
- whether the 310 ml or 600 ml package fts the intended dispensing equipment.
Frequently Asked Questions
What is the difference between TP702 and TP703?
TP702 is Victor Sealant’s windshield polyurethane sealant for evaluating automotive glass-related joints. TP703 is Victor Sealant’s automotive body panel and body-joint polyurethane sealant for metal bonding, weld joints, van joints, and related automotive sealing applications. It should be selected according to the joint function and substrate system.
Is TP703 suitable for windshield bonding?
Do not assume that TP703 is suitable for a windshield joint because it is a polyurethane sealant. TP703 is positioned for automotive body metal bonding and body-panel sealing. A windshield project should be evaluated with TP702 or another product specifically documented for the glass-to-frame application.
Is TP702 suitable for automotive body seams?
Do not assume that TP702 is suitable for body seams simply because it is used in automotive glass-related work. TP702 is positioned for windshield polyurethane sealing. Body seams, welded joints, and metal panel connections should be reviewed with TP703 or another product documented for that function.
What substrates should be checked before approving TP702?
Confirm the windshield glass, ceramic or frit surface where applicable, frame material, metal primer, lacquer or coating, cleaning process, bead dimensions, and dispensing method. The final combination should be checked against the current TDS and project instructions.
What substrates and applications should be checked for TP703 automotive body joint sealant?
Review the exact body metal, painted or coated surface, welded joint, panel connection, van joint, or bus air-conditioning installation. Confirm water exposure, movement, abrasion, paint compatibility, bead orientation, and curing conditions.
What packaging is listed for TP702 and TP703?
The published product pages list 310 ml and 600 ml packaging for both models. The buyer should confirm the final package format, pallet configuration, storage conditions, dispensing equipment, MOQ, and delivery schedule.
Can Victor Sealant provide OEM or private-label automotive sealant supply?
Victor Sealant presents automotive sealant solutions for OEM and aftermarket supply and provides an OEM/ODM channel. Distributors should submit the selected model, target market, package format, label language, annual quantity, documentation requirements, and destination for a feasibility and quotation review.
Contact Victor Sealant for TP702 windshield sealant and TP703 body sealant samples, TDS/SDS, OEM packaging, and bulk quotation. Send the joint type, substrate combination, project market, and expected quantity so the technical and sales teams can prepare a product-specific response.
