- Register covers
- Recessed lighting
- Door, window and cabinet seals
Excellent Shear Holding Strength with 3M™ Adhesive 430
3M™ Urethane Foam Tape 4314 features 3M™ Adhesive 430. This pressure sensitive, modified acrylic adhesive provides high initial quick-stick to a variety of surfaces and substrates. It has an excellent chemical resistant and shear holding strength, even at elevated temperatures. Adhesive 430 is designed to perform at temperatures up to 180°F (82°C) in the short term and 150°F (70°C) long term.
Protect Sensitive Components
The adhesion of 3M™ Single-Coated Foam Tapes is typically satisfactory within 20 minutes and continues to build with additional time. The adhesive is protected by a thick, silicone treated paper liner and has a firm, high-density foam. This design offers an attractive and clean appearance after application.
What is Open Cell Foam?
Open cell foams are commonly used between component panels where a degree of separation is needed to dampen or prevent vibration, as a thermal insulation barrier and to protect against contamination, but where a measure of airflow is still necessary, such as with electronic components where air flow helps keeps components cool.
