These products are suitable for door, window and general sealing and vary in strength, flexibility and skin/open times. 

Truck, bus and RV sealant: technologies

Silyl-modified polymer (SMP)

Bostik has been the market leader in SMP technology in the transport market for over 25 years. 

Laboratory tests show that SMP technology has a much higher UV resistance than polyurethane technology. This property makes it ideal for sealing the windows and body construction of trucks, buses and RVs. 

SMP products also save time in the painting process. Paint can be applied after the bead has formed a skin layer; while polyurethane sealants need to have fully cured prior to painting. 


Our one-part urethane sealants offer fast-set solutions that cure with atmospheric moisture to form a tough, flexible seal. PU products are well-suited to RV, truck trailer, emergency vehicle and bus applications. 

Butyl sealants

Our non-hardening mastic sealants are designed to form a weatherproof and dustproof seal, which stays permanently flexible. Bostik butyl sealants are a popular choice for restoring vintage caravans.
