SIMSON primer and cleaner

Primers are not absolutely necessary for use with SIMSON adhesives and sealants.
On all smooth, clean, dry and oil-free surfaces (metal, painted surfaces, glass, PVC, GRP)
a good bond is possible primer-free.

Primers are recommended in the following cases:
Primer SIMSON M: With smooth problematic surfaces or with surfaces
expected to have high dynamic loads, Primer M should be used. SIMSON M is a
wash primer that serves to degrease surfaces and to promote adhesion.
Primer SIMSON P: With unfinished wood surfaces or other porous absorbent
bases (masonry, concrete), Primer P should be used.
Cleaner SIMSON E: Cleaning tools and degreasing surfaces for bonding.

Primer requirement: approx. 50 ml per 290 ml cartridge.
