How do you mix zinc phosphate primer?

How do you mix zinc phosphate primer?

Mixing Paint Stir CapaEpo Zinc Phosphate Primer with a low-speed stainless steel agitator. Do not use mixers made of aluminium – danger of discolouration. Use as little Epoxy thinner as possible to achieve application consistency. Stir well before application.

What is zinc phosphate epoxy primer?

Epoxy zinc phosphate primers contain zinc phosphate, which acts as a corrosion-inhibiting pigment. Epoxy primers are used to waterproof materials that consequently protect the bare metal from oxidation. A dry, very clean surface is needed before applying an epoxy primer.

How do you make epoxy primer?

To prepare the epoxy primer, shake or stir the primer following the instructions on the label, then thoroughly mix one part primer with one part catalyst. To reduce any film buildup, this one-to-one ratio can also be cut with a urethane-grade reducer or comparable solvent solution.

Why is zinc phosphate mixed increments?

The reaction between zinc oxide and phosphoric acid is exothermic and requires a strict mixing protocol to control excess heat generation. A small increment of powder is first mixed to reduce the acidity of the liquid. Subsequent increments of powder are added, and the heat also increases.

What is zinc phosphate primer used for?

Zinc Phosphate Primers are steel primers formulated with zinc phosphate, a mineral that offers inhibitive or active corrosion protection to protect the steel substrate from corrosion. They act differently from other forms of corrosion protection.

Is zinc phosphate a good primer?

Armstead Trade Metal Primer Zinc Phosphate is a professional quality metal primer that has excellent adhesion and inhibits rust, preventing the spread of corrosion. It is generally resistant to heat up to 90°C.

How do you dilute epoxy primer?

Dilute 1:1 ratio with Boysen® Epoxy Reducer #55. Apply as primer coating on bare concrete. Let dry overnight.

What is epoxy primer hardener?

Hardener component of a primer sealer that provides excellent corrosion resistance over multiple substrates. As a sealer, this product provides excellent leveling with superior gloss retention.

What is 2K epoxy primer?

2K Epoxy Primer Sealer/Groundcoat is an exceptional lead and chromate free corrosion-resistant coating with excellent adhesion on a variety of properly prepared surfaces. 2K Epoxy Primer Sealer/Groundcoat improves adhesion of body fillers and resists moisture damage caused by water permeation.

What thinner is used for epoxy primer?

Adding 5% lacquer thinner to epoxy reduces epoxy’s compressive strength by 35%. As such, it’s no longer suitable as a structural adhesive. Adding a solvent can extend curing time, making your work unpredictable. Adding a solvent can cause the epoxy to shrink and crack over time.

Which thinner is use for primer?

Oil-based paints frequently require “thinning” to reduce their viscosity, or thickness, to improve flow and shorten drying time. If primer requires thinning prior to application, the paint can be mixed with a commercially prepared paint thinner made up of petroleum distillates.

What is the difference between 1K and 2K epoxy primer?

1K – suited to interior use, low traffic areas, and places less prone to general wear and tear. 2K – suited to exterior use, heavy use areas, high temperature surfaces and other harsh environments.
