H1010# Epoxy Primer For Iron Plate (2K)

Product Description

H1010# Epoxy Primer For Iron Plate (2K)
Composing:
It is a kind of two component protective primer that is made from modified epoxy resin, rustproofing pigment, mica fillers, organic solvent, etc. with H1110 hardener according to the proportion of 4:1.    

Characteristics:
This primer has excellent adhesive force and rigidity. It can fast dry at normal temperature; it has good capacity of elasticity and extension to deformation generated by the temperature change of substrate, good mechanical character, and anticorrosive property.

Field of Application:
This product is applied to metal products that request to anticorrosive property, anticorrosive coatings of car body, car frame, car box and car bridge of bus, as well as the primer of iron plate, electrolytic plate, aluminium alloy and other nonferrous metal products and glass fiber reinforced plastic. Also can be as anticorrosive coatings of nonmetal surface.

Reference for construction and notes:
1.It is suitable for spray coating and brush coating. Implement the rust removing treatment to substrate before construction (spray sand to grade Sa2.5, surface roughness 30~70μm).

2.Mix well H1010 epoxy primer and H1110 hardener according to the proportion of 4:1, keep curing for 20min (room temperature), use H1210 thinner to dilute for 18~20s (T-4, 25 Degree centigrade), wet-to-wet spray painting twice, dry for 12 hours (or 1H/80 Degree centigrade). After drying, scrape putty or spray intermediate primer and finishing paint.

3.Mix paint every time according to construction using amount, the paint that has mixed into hardener should be used up in time (use for 5 h at normal temperature), or it will be discarded due to becoming thicker.

4.This primer can dry by itself at normal temperature, the film coating performance will be better when baking dry, the usually condition of baking dry is 80 degree centigrade, 60 minutes.

5.The storage life is one year from the date of commencement of production (if it is beyond the storage life, please confirm according to the standard inspection; if it is still qualified, it can be continuously used).

Packing and Storage:
Packing Specification: Primer is packed 4L printing iron drums. Hardener is packed 1L printing iron drums.
Storage Condition: 5-35 degree centigrade, store in a cool, dry well-ventilated place.
