PRIMARY MASTIC ADHESIVE INSULATION (SHC 104-90)
Primary Mastic Malaysia : Every Construction Project’s Best Choice
Our primary mastic serves as an adhesive and sealant for construction projects. It is widely used in circumstances where a surface requires to be adhered to another in a durable bond, or where the area requires to be protected.
The most common types of materials our primary mastic can be adhered to include timber, aluminium, steel, marble, glass, and varying types of board. Though, it can be used on nearly every material.
Some of Its Main Applications :
- The ideal finish for cold insulation including cellular glass, PIR
- Tough, flexible, fire-resistant elastomeric finish
- Excellent vapour barrier
- Outdoor use with good colour retention, chemical and UV resistance
SHC 104-90/91 is a chlorosulfonated polyethene (CSPE) rubber based mastic.
