Rosin based blocking pitches

Types available: A, B I, B III, B III/OF, AKP 1010, AKP 1040 These blocking compounds with low melting point mainly consisting of rosin, maleinates, natural softening agents and mineral fillers are suitable for low-tension applications. Rosin provides an excellent adhesive strength.

Rosin compounds are particularly suitable for gluing plano-optic components to substrates and grids. High strain can be avoided due to their low softening points. BIII with fillers is supplied at different hardness. B III, AKP 1010 as well as AKP 1040 are especially for temporary cementing at short-run production, for doing corrections and for blocking.
