Technical Information

CURE MECHANISM

SikaGlaze IG-5 PIB-2 is a non-reactive polyisobutylene and stays paste-like and viscoelastic.

Application

Method of Application

METHOD OF APPLICATION

Surfaces must be clean, dry and free from grease, oil and dust.

Surface preparation

SikaGlaze IG-5 PIB-2 must be heated-up to the required application temperature before being applied by the extruder. Preliminary application tests to set up the equipment are mandatory.

Removal

SikaGlaze IG-5 PIB-2 may be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water.

Do not use solvents on skin.

 

Application limits

Recommended solution from Sika for insulating glass production are usually compatible to each other. These solutions consist of products such as Sikasil® SG, IG, WS and WT series. For specific information regarding compatibility between SikaGlaze IG-5 PIB-2 and other Sika products contact the Technical Department of Sika Industry. To exclude materials influencing SikaGlaze IG-5 PIB-2, all materials such as gaskets, tapes, setting blocks, sealants, etc., in direct and indirect contact have to be approved by Sika in advance.
