How to Effectively Prevent Clear Resin from Yellowing

Is it possible to get clear epoxy resin that doesn't yellow over time

(We only talk about the none-color clear resins on this article but not the resin in colors, because many clients love the crystal transparent looking from the new table but worrying it will fade to yellow during years)                                 

How Resins Behave Over Time                                                                       

 Epoxy resins change with exposure to UV light (as most things on earth do!). Even fluorescent indoor light can cause it to change. The most noticeable change is in respect to color. When UV light hits a resin coating, it degrades the epoxy polymers, causing ambering (i.e. a noticeable yellow discoloration). Even resin that may have started out crystal clear will soon turn a yucky yellow hue. This process and outcome is inevitable, unless something is done to the chemical make-up of the resin formula to address this.

What is a UV Stabilizer and How Does It Work?               

 Many epoxy resins on the market include a UV stabilizer to protect against yellowing, as well as other problems that epoxies are prone to (such as de-lamination, chalking, cracking and gloss loss). In truth, a UV stabilizer is necessary and effective, except when it comes to the yellowing issue. A UV stabilizer merely delays yellowing... another additive altogether is required to really combat yellowing— something by the name of Hindered Amine Light Stabilizer (HALS). Unlike UV light stabilization, Hindered Amine Light Stabilization (HALS) actually interrupts the yellowing process at the outset, making it much more difficult for yellowing to occur. HALS has been demonstrated in numerous test cases over the years to be extraordinarily effective in protecting against yellowing —there is approximately 50 years worth of this evidence available.

What does Mooka do about it?

 There is none existed epoxy resin can really not turning to yellow the world. But since 2016, Mooka has been working with China SINOPEC to study the best formula which including the UV stabilizer and HALS stabilization, called SINOPEC synthetic resin. SINOPEC synthetic resin was developed specifically for use over river tables and craft projects, meaning it has been formulated to keep the crystal resin as long as possible, normally 1 years longer than the other brand resin on the market,as a matter of scientific fact, amber and yellow over a period of a few months. A low quality resin product applied over river table will deteriorate the work and decrease its value, leaving both artists and patrons frustrated and disappointed. In that sense, choosing to use a cheaper resin product is actually an extremely costly mistake. SINOPEC synthetic resin has been certified as safe for home use by an ASTM board-certified toxicologist and contains no VOCs or fumes.

On top of all this, our formula SINOPEC synthetic resin is also safe for home use when used as directed ( that is, in a well ventilated area ), it's self-leveling, it has a bubble release agent, it's an easy-to-use .We worked with a chemist for 5 years to get this picky list of specs into one formula.  We're excited about it because it's the product we were searching for our own river table purposes , and that it is!
