In fact, it is better to use hard rubber as resin luminous characters. The yellow resistance of this hard rubber is generally 3-6 months better than that of soft rubber, and the adhesion is better. Soft rubber is just easy to maintain. The most commonly used hard rubber with low hardness has excellent yellowing resistance! The difference of soft rubber is that it is not easy to crack when making big characters.
Generally, we use hard glue the most. Hard glue is suitable for making small words and more, and it is easy to dry. Small words are often used indoors and are not affected by temperature. There is another difference between hard rubber and soft rubber. Soft rubber is often used in the cold winter in the north because
When the temperature is low in winter, hard rubber is easy to crack or degum.
We usually use indoors, which will not be affected by high temperature. The indoor temperature generally does not exceed 30 degrees, and there will be no cracking and degumming.
Soft rubber only uses outdoor characters, but there are few characters or almost all manufacturers dare not do it! Large characters refer to characters above 1.5M, because the shell made of such large characters will be very uneven, and it is difficult to flatten the glue if the shell is uneven. In addition, the glue pouring area is large, the load bearing capacity is also large, and the transparent acrylic on the surface is easy to fall off, so that the word shell and glue will fall off and separate! If such a problem occurs, it will be very serious, because Chinese characters are generally installed outdoors, and the glue and shell glue will fall off.
