KF-BT100 Butyl Sealant Tape

KF-BT100 butyl sealing tape is a self-adhesive sealing tape made primarily of butyl rubber and using polyisobutylene as an tackifier. It is weather-resistant for over 12 years without hardening or cracking. It is widely used for waterproofing and sealing joints in steel structure roofs, curtain walls, polycarbonate panels, and ventilation ducts.

CoreAdvantages

Butyl rubber - permanent elastic

Butyl rubber (IIR) has a high molecular chain saturation and no double bonds in the main chain, giving the sealing tape excellent weather resistance (20 years) and permanent elasticity. It remains flexible at -40 degrees Celsius and does not flow at 100 degrees Celsius. It is resistant to UV rays, ozone, acids, and alkalis.

Self-adhesive, quick to install

The sealing tape is coated with high-viscosity pressure-sensitive adhesive; simply peel off the release paper and apply directly. No primer, heating, or special tools are required. It conforms well to various shapes and can be applied to irregular and curved surfaces. Application efficiency is 5-10 times that of liquid sealant.

Waterproof sealing for all kinds of scenarios

Sealing for steel structure roof panel overlaps, aluminum curtain wall panel joints, polycarbonate and skylight panel joints, ventilation duct flanges, door and window frame to wall joints, container and mobile home joints, and vehicle and ship sealing. One application saves time and effort by stopping leaks.

ApplicationProcess

1

Surface preparation

Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。

2

Primer / pre-treatment

Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.

3

Main-coat application

Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.

4

Curing process

Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.

5

Inspection & acceptance

Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
