Description

This CLEAR RIGID EPOXY RESIN system is specially formulated for decorative applications including casting.
It is totally clear and UV stabilized giving excellent optical properties with negligible to no shrinkage on curing.

 Preparation
It can be used for casting decorative parts featuring a long working time, ease of use and low exotherm. Ensure ambient material and workshop temperature is between 18 to 25ºC and humidity level below 70%.

 Mixing by Volume
Mixing is critical and must be accurate. 2 parts resin for 1 part of hardener will provide a hard casting once cured. Pour the hardener first then the resin. The combined liquids must be thoroughly mixed manually or mechanically to completely remove any haziness or streaks, scraping the sides and base of the mixing pot then transferring the mix to a second container and stirring is best practice for good castings. An entirely homogeneous mix is essential in achieving optimal results. It is important to only mix the correct quantity at a time as epoxy systems tend to exotherm when kept in a mass.

(Mixing by weight: 100g resin to 42g hardener pro rata).

 Application
It can then be poured into a mould. The mould can be a hard mould or made of silicone rubber. Moulding can be carried out by gravity or under vacuum. It does not trap air easily and does not heat up when used properly. Temperature should be between 18 to 25ºC. Humidity level below 70%. Pot life is as follows for a 500g mix at 22ºC 2+1 mix=10 hours. The hard mix (2+1) will provide a hard casting, suitable for manufacture of fancy shapes, decorative items etc. Should a new mix be applied onto cured resin, the contact surface should always be sanded in order to enhance adhesion.

 Curing
Parts can be released after the following time at 22ºC. 2+1 mix =19 hours

Health & Safety.
This product is a modern formulation of the safest epoxy chemicals available. It is however advised to follow basic rules such as avoiding skin contact, wear masks when producing dust.

 TROUBLESHOOTING

 PROBLEM                                                CAUSE

Cloudy or solid state in container:                 Storage below 10ºC.

Uncured after 24-48 hours:                           Wrong mix ratio and/or                                                                temperature low.

The mixture gets hot:                                    High temperature and/or too                                                                much mixture was prepared.

Air bubbles are entrapped:                            Mixing was too fast and did                                                                not have time to release air.

Sticky, greasy surface:                                  Humidity level is too high.

PACKING & STORAGE

 Shelf life is one year in sealed containers as provided. Keep containers sealed and away from heat and cold.
