3M 08682
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium
Main features
- Automotive Urethane Adhesion Primer
- Fast-Drying No-Activator Processing
- UV-Blocking Corrosion-Protection Primer
Product Description
3M™ Single Step Primer 08682 is a one-component polyurethane-based primer designed to promote adhesion between 3M urethane windshield adhesives and automotive glass, primed pinchweld metal, and PVC encapsulated parts. It also functions as a blackout primer to help protect urethane adhesive from ultraviolet exposure while providing corrosion protection for minor pinchweld scratches. The fast-drying formulation requires no activator and is intended for professional automotive glass installation applications. :contentReference[oaicite:0]{index=0}

Viscosity

Viscosity is a measurement of a fluid’s resistance to flow.
Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.
A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.
The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application
