EP 3225 Black Fast cured Epoxy structural adhesive
Maxtech EP 3225 series epoxy adhesive is a two-component room temperature curing epoxy resin. Designed for bonding ceramic, metal, glass, plastic, rubber, paper, cloth and other materials.A and B components are thoroughly mixed 1:1 (weight ratio or volume ratio) before use. The product has good toughness and aging resistance after curing, and the adhesive layer is not easy to be brittle after curing. At the same time, it has certain resistance to ultraviolet light and moisture, and can be used for local potting and bonding of outdoor mechanical equipment.
The cured adhesive has the following characteristics:
*Resistance to moisture, dirt, and other atmospheric components
*High strength, excellent adhesion
*Good pollution resistance, low surface pretreatment requirements
*No solvent, no curing byproducts
*Stable mechanical and electrical properties between -50 and 120℃
*It has good adhesion to plastic PC, glass fiber cloth and steel plate
