Description
Permabond TA4605 is a two component, 1:1 toughened acrylic adhesive developed to bond low-surface energy plastics with no primer or surface treatment. It can also be used to bond a variety of other materials including composite or metal and is ideal for bonding dissimilar surfaces. 1:1 mix ratio by volume, Off-White, 50 mL Kit.
Great bonder for hard-to-bond surfaces like various rubbers, HDPE, UHMW, LDPE, LLDPE, polyolefins
TA4605 is a substitute / backup formula for these formulas:
- 3M DP8005
- 3M DP8010
- Scigrip SG400 LSE
Features and Benefits:
- Adhesion to a wide variety of substrates
- Thick Gel Formula, Thixotropic, Non-Sagging, Gap-Filling
- Full cure at room temperature
- Set time is 5-10 min
- Bonds to polyolefins
- No primer required
- No need to flame-treat or plasma treat-surfaces before bonding
- Excellent impact & sheer strength
- Excellent chemical resistance
