by zinc powder, epoxy resin, curing agent, additives and so ent.it a two-component epoxy zinc-rich primer.
Second, major features:
1.film contains a lot of metal zinc powder, has the cathodic protection.
2.excellent rust resistance and durability
3.has excellent adhesion and impact resistance performance
4.has excellent wear resistance
5. has excellent extensive oil resistance and so ent resistance performance
6. quick drying
7.with most high performance can paint and supporting the use of paint
for the port and dock, mining machinery, oil, water conservancy machinery, gas tank outside wall, heavy machinery and other steel structure and shipping lanes over parts. Film thickness in the specified scope, can be in shipyard, heavy machinery factory of the place such as steel pretreatment line as a shop primer, maintenance period for about nine months.
Four, performance and parameters:
1, color appearance: gray light
2, the basic parameters: density about: 2.30 g/cm3 (mixed)
3, matching: a (paints) : b (curing agent) = 100:15 (weight than)
4, dry film thickness: 20 μ m
5, theory usage: 135G/ m2
6, flash point: a division (finishing) 24 °C, a junior group b (curing agent) 27 °C
7,dry time (25 °C): more than 5 min work table dry more than 24 h to cure the7d assembly line drying time more than 5 min (steel 50 °C, preheat the baking temperature 120 °C).
8, age 25 °C) time: (30 min)
9, suitable period: (mixed)
(1) temperature: 5 °C 20 °C 30 °C
(2) suitable period: 12 h 8 h 6 h
Five, coating methods:
brush, roller coating, air spray, high pressure without gas spraying all can do.
1 nozzle diameter: (1) high pressure without gas spraying: 0.4 0.5 mm; (2) air spray: 2. O-2.5 mm.
2, gushing pressure: (1) high pressure without gas spraying: 15-20 MPa; (2) air spray: 0.3 0.4 MPa.
102 special thinner,; Amount of thinning: 0-20% (in paint weight plan).
Seven, that after supporting coating: with epoxy micaceous iron primer, epoxy asphalt, chlorinated rubber antirust or face paint etc supporting the use.
Eight, surface treatment:
used for workshop assembly line, steel surface is is shot or sandblasting processing methods, remove scales, rust, requirements to Sweden derusting standard Sa2.5 level or manual derusting St3 level reached.
Nine, construction condition:
substrate temperature shall be above 3 °C above the dew point, relative humidity should be less than 85%. Construction substrate temperature below 5 °C epoxy firming agent and when to stop reaction, can't construction.
Ten, advice coating word count:
no gas spraying a the dry film thickness of 15 ~ 20 um.
Eleven, the storage period:
twe e months.
Twe e, note:
zinc powder content high, so for deployment in the recommended to use mechanical agitation mix of the division, then add in the following a stir well; In high temperature season when construction, easy to occur dry spray. To prevent dry spray phenomenon, must join thinner to adjust so far not spray; Zinc-rich primer formed surface is easily zinc salt in coating, coating, that after before to eradicate the surface zinc salt, otherwise it will affect the paint film adhesion between the layers.
the above this product information and data is according to our test and actual the experience of accumulating and can be used as a guide for construction. For we do not understand in the construction, our factory only guarantee that the quality of the paint itself, will not be responsible for other aspects. This specification, and we will be according to the continuous improvement of products shall have the right to make changes.
