Diluent tolerance

PLAXTENE LWA XWA resins can be diluted with alcohols, esters, and glycol ethers

and their esters. They have limited diluent tolerance for aromatic

hydrocarbons and none at all for white spirit.

Compatibility

PLAXTENE LWA XWA resins are compatible with cellulose nitrate, urea resins and

epoxy resins.

Application

PLAXTENEresins are used either as sole binders for acid-catalyzed and

baking finishes or in combination with cellulose nitrate.

PLAXTENE XWA AND LWA produces extremely flexible coatings on pliable substrates

(eg, rubber, textiles, paper etc).

Baking finishes with PLAXTENEresins are cured at 120 ­180 °C to

produce non-yellow finishes. Urea-formaldehyde formulations are not

recommended for articles that are continuously exposed to moisture.

The properties of the resin and the finish depend on many factors

for us to take account of in our own trials. Formulator's own paint trials are

therefore essential.

Safety

General

Attention must be paid to the normal precautions for handling chemicals

and to the measures prescribed in the local health regulations. The work-

place must be well ventilated, skin care measures should be adopted and

eye protection should be worn.

Safety Data Sheet

The Safety Data Sheets for PLAXTENEresins provide information on all

the known safety data.

Storage

PLAXTENE resins have a shelf life of 12 months if kept cool (but away

from frost) in tightly sealed drums or storage tanks.

Note

The information submitted in this publication is based on our current

knowledge and experience. In view of the many factors that may affect

processing and application, these data do not relieve processors of the

responsibility of carrying out their own tests and experiments; neither do

they imply any legally binding assurance of certain properties or of suit-

ability for a specific purpose. It is the responsibility of those to whom we

supply our products to ensure that any proprietary rights and existing laws

and legislation are observed.
