LORD 7100A
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- High-Strength Structural Bonding
- Primerless Bonding to Many Plastics
- VOC-Free Weathering/Aging-Resistant Urethane
Product Description
LORD® 7100-A/B Urethane Adhesive is a two-part, high-strength urethane adhesive formulated for bonding cloth, paper, plastics, foams, rubber, painted metals and powder-coated metals. The system combines an isocyanate-based 7100-A resin with a polyol-based 7100-B curative and can be cured at room temperature or with elevated heat for faster processing. Once cured, it forms a glossy black bond with resistance to solvents, weathering and aging.
Key Features
- Broad substrate capability for cloth, paper, plastics, foams, rubber, painted metals and powder-coated metals.
- High-strength plastic bonding without crazing, attacking or reducing the strength of the plastic substrate.
- Primer reduction on many plastics to help lower material and labor requirements.
- Solvent-, weathering- and aging-resistant performance after cure, with no VOC content or ozone-depleting chemicals.
Applications / Suitable for
- Plastic and foam assemblies
- Rubber bonding
- Cloth and paper laminations
- Painted-metal and powder-coated-metal assemblies
