HRC110 - Adhesion promoter for polycarbonate and Lexan - Hikari RC

Lexan® Body Primer is a clear adhesion promoter specially designed for this highly resistant and flexible polycarbonate plastic.

This primer acts as a glossy acrylic-polyurethane Topcoat, ensuring guaranteed adhesion on Lexan®, even without sanding.

It provides superior grip for our special Lexan paints (opaque or pearlescent ranges).

Ideal for protecting paintwork inside radio-controlled vehicle hulls and fairings subjected to extreme stress and impact — such as stone projection, torsion, heat, shock, and abrasion.

With the Lexan® primer, the paint becomes absolutely inseparable from the plastic.

Composition : Water-based compound containing no more than 3% solvent.

Non-dangerous and non-toxic product.

Appearance

In liquid form, the product is whitish. When dry, it becomes transparent and glossy.

For this reason, it can also be used as a varnish.

Its resistance is exceptional, both to detergents and abrasion.

Use :
Usually applied as a first coat, directly on the inside of transparent Lexan hulls.

Additional Tips to Promote Optimal Adhesion:

Alongside our Lexan adhesion primer, we recommend using our Lexan plastic preparation cleaner.
You may also use a grey abrasive sponge to lightly deglaze the plastic before applying the primer.

Coverage and Intercoat Adhesion:

When applying a new coat of paint (opaque or metallic) over the primer, proceed "wet on wet" — that is, while the primer surface is not yet fully dry.

This interval ranges from 5 minutes to 48 hours, though the best adhesion (without sanding) occurs within the first two hours.

If you need to carry out decoration or masking work, allow the primer to dry completely to the touch (around 2 hours), then sand it lightly with P500 before painting.

Respecting this intercoat adhesion rule is essential to prevent delamination: you may obtain excellent adhesion to plastic, but if the subsequent coats do not bond properly, they will eventually detach from the primer.
