Professional adhesive for porous
3M 21187 Contact Cement is a water-based adhesive designed for bonding porous and non-porous materials. The 30NF series formula provides a long bonding range suitable for professional applications. It arrives in a 5 gal pail ready for brush, roll or spray application. The green colour helps visibility during application.
Sustained load performance
The adhesive offers a 30 min working window that allows precise alignment before the bond sets. Heat resistance is rated to 180 Degrees F for durability in warm environments. Maximum application temperature reaches 200 Degrees F during use. Viscosity is capped at 750 cps for consistent flow across large surfaces.
Low odour and nonflammable with low VOC content
This water-based formula is nonflammable and carries a VOC content below 80 g/L for reduced emissions. Low odour improves comfort during extended indoor use. Water-resistant bonds maintain integrity after exposure to moisture. The product ships without state sales restrictions.

Questions about this item
Does the 30NF contact cement give off strong fumes or heat while curing during a full workday?
The adhesive is low-odour and non-flammable, so it does not produce strong fumes or heat during its 30-minute working time and cure.
What substrates or primers must I already have on hand for the 21187 cement to bond properly?
It bonds porous or non-porous surfaces directly — wood, metal, laminate and many plastics — with no separate primer required.
Will the 30NF series hold up next to older solvent-based adhesives already in the shop when exposed to 180 °F service heat?
Yes, it remains heat-resistant to 180 °F and water-resistant, so it performs alongside legacy adhesives in high-temperature areas.
