BETASIL ZSP GZ 2

Description :

Betasil ZSP GZ 2 is two pack, self curing solvent based inorganic zinc silicate coating.

Recommended Use :

As a general high performance rust preventing primer for long term protection of steel surface against rust and corrosion.

Features :

• It withstand temperature up to 400⁰ C/750⁰F.
• Excellent corrosion resistance
• Good abrasion resistance

Physical Data :

Recoating Interval :

Betapox (System/high build ) : 36 hours (25⁰C, 77⁰F, 75% RH).
Betapox (25 microns/1 mil ) : 24 hours (25⁰C, 77⁰F, 75% RH).
Betanyl ( System/high build ) : 48 hours (25⁰C, 77⁰F, 75% RH).
Betanyl (25 microns/1 mil ) : 24 hours (25⁰C, 77⁰F, 75% RH).

The overcoating interval of 24 hours for 25 microns/1 mil Betapox or Betanyl is only valid in case subsequent coat is applied more than 3 days after the first thin coat, otherwise as for system/high build.
Overcoating is expected to take place within 6 months after application of Betasil ZSP GZ 2.

Surface Preparation :

All welds must be free from pinholes and all welds spatter must be removed. All sharp edges must be rounded off or removed in such a way that the paint film thickness can be built up on all surfaces. Gritblasting to minimum Swedish standard S15 055990 Sa 2.5 (SSPC – Sp 10) with a surface profile equivalent to regotest No.3 BN 10a to BN 11 or Keane – Tator valley roughness 75 microns/3 mils).
When blasting is completed, remove residual grit and dust by vacuum cleaning.

Curing Conditions :

From 10⁰C/ 15⁰F to 40⁰C/ 105⁰F.
Curing needs minimum 50%, preferably above 65% relative humidity. Drying time are strongly dependant on both temperature and humidity and deviations from the standard conditions may shorten or prolong the overcoating interval.

Precautions :

This product is flammable, keep away from heat or open flames.
As general rules, inhalation of solvent vapors or paint mist and contact of liquid paint with skin or eyes should be avoided.
Forced ventilation should be provided when applying in confined spaces. Respiratory, skin and eyes protection are always recommended.
