PRIMER® 1
PRIMER FOR POLYURETHANE BASED FLEXIBLE SEALANT SYSTEMS

Description

PRIMER 1 is a transparent liquid based on polyurethane resins, solvent based, which is used to improve bonding of polyurethane flexible sealants such as MAXFLEX 100 LM, MM and HM, as well as the self levelling MAXFLEX 700 and 800.

Uses

- Primer for sealing systems with polyurethane products for joints
- Submitted to important stresses and movements
- Applied on porous substrates.

Application

Preparation of the substrate: PRIMER 1 must be applied on dry, surfaces, free of dust, grease or rust, etc. The substrate surface must be between +5º C and + 40º C.
Application: The application must be done prior to placing the MAXCEL backing rod, because the solvent contained in PRIMER 1 could damage it. Apply PRIMER 1 on the inside of the joint edges, being especially careful to apply uniformly a small thickness. The primer should be protected from dust, humidity and dirt for as long as the drying lasts.
If the substrate were excessively absorbent, a second priming layer can be applied once the first one has dried.
Because of the sensitivity of PRIMER 1 to atmospheric humidity, it is very important to close the container well after each use. It is advisable to pour the necessary amount for the job into another container and to dispose of any leftovers when finished. The apparition of sediments or a murky aspect in the liquid is the result of the hydrolisis of the active principles of the PRIMER 1, in which case it is not advisable to use it.
Finish of the joint immediately after the PRIMER 1 has dried, in order to prevent the dusting of the primed surface.
