TULDA PT30 MULTIPRIMER 4+1 HS Acrylic Primer Kit

Technical Data Sheet 400003129
Characteristics:
HS Acrylic Primer / Filler 4+1 a filling primer based on acrylic resins. Thanks to a high spray
viscosity, the product can be applied in very thick layers that perfectly repair even relatively large
scratches and irregularities of substrate. The product has a very good adhesion to various
substrates and short drying time. It is easy to treatment, has excellent sanding and good filling
properties – an ideal substrate that guarantees excellent appearance of coatings.
Substrates:
– old paint coatings (including thermoplastic paints),
– polyester putties,
– steel,
– aluminium
– stainless steel,
– wash primers,
– epoxy primers,
– plastics
– polyester laminates.
Substrates preparation:
– old paint coatings: degrease and sand dry P220 – P360,
– polyester putties: finish sand dry P240 – P320,
– steel surfaces: degrease, sand dry P120 – P240,
– stainless steel: degrease,
– plastics: clean with a Silicone Remover and matt using abrasive needled cloth. Again degrease,
apply Adhesion Increasing Agent and Elasticity Increasing Agent
– polyester laminates: degrease and sand dry P280
Colour matching:
Various colour acrylic topcoats can be used. Do not exceed 15 % by volume. Hardener should be
calculated on the whole amount of the colored filler.

Procedure:
Apply two or three single wet layers leaving 5 ÷ 10 min time for evaporation after each one.
Evaporation time depends on the temperature and the thickness of the layer. 10 min after the last
layer was applied the coat can be force-dried.
