Estelan AR

1. Description

ESTELAN AR is a universally applicable two-component screen lacquer which is highly resistant to solvents and chemicals. It is used the edges of the mesh and to protect the screen adhesive from aggressive solvents.

Mix ESTELAN AR in a 3:1 weight ratio with the corresponding HARDENER RD by mixing 100% ESTELAN AR and 33.5% HARDENER RD. After stirring thoroughly, the lacquer can be applied with a brush or a coating trough.

The potlife of the mixture is approximately 12 hours at 70 degrees Fahrenheit.

WARNING: ESTELAN AR may attack frame adhesives if they are not cured properly. See technical data sheet for KIWOBOND frame adhesives.

Extreme conditions or continuous exposure to solvents in screen washing units may require an increase in the hardener proportion to 1:1. However, elasticity of the lacquer is somewhat reduced, therefore, it should not be coated onto the mesh itself.

2.1. Drying / Curing

The drying time depends on environmental conditions and varies between 1-2 hours. For chemical resistance the lacquer needs a reaction or curing time of approximately 48 hours at 70 degrees Fahrenheit. The curing time can be shortened by heat setting the DRY lacquer at elevated temperatures.

Curing at 130 degrees F: approx. 8 hours

Curing at 175 degrees F: approx. 2 hours

2.2. Cleaning / Removing

Cured ESTELAN AR is generally difficult to remove; therefore clean tools immediately after use with a general cleaning solvent.

Removal from the screen is relatively easy if used in combination with KIWOBOND frame adhesive. Simply peel the mesh of the frame. WITH other adhesives or if applied in thick layers use PREGAN DL or remove the lacquer / mesh with a sander.

ESTELAN AR and HARDENER RD are highly flammable. Keep away from sources of ignition. DO NOT SMOKE. Do not breathe fumes. Working areas must be well ventilated. Avoid contact with eyes and skin. Wear chemical-splash eye goggles and protective gloves. Use respiratory protection if exposure limits are exceeded. See Material Safety Data sheet for additional information.

Do not empty into drains. Completely hardened and dried lacquer can be eliminated as non-hazardous solid waste. Consult your local authorities for local regulations.
