RT2315 Hot Melt Candle Glue

Hot melt candle glue is an adhesive that anchors wick clip assemblies to the bottom of empty container candles. It is typically a blend of different polymers that melts when heated to a very high temperature allowing it to be deposited within the container. Once it cools and solidifies, it forms a bond that anchors the wick clip assembly in place during the pouring of liquid wax and repeated burn cycles.

What is RT2315 Hot Melt Glue for Container Candles?

RT2315 is a specialty hot melt Hot-melt-candle-glue-Wicks-Unlimitedcandle glue supplied by Wicks Unlimited to safely and securely anchor metal wick clip assemblies inside empty candle containers. This glue has been successfully tested to withstand the high temperatures encountered on and around the container’s base, especially while pouring, the candle’s final burn cycles, and subsequent end of life.

One of RT2315’s most sought-after benefits is its heat resistance. This vital attribute minimizes the chance of the phenomenon known as wick migration, where the wick can slide from its original anchor point during pouring or when the burn pool temperature is elevated towards the candle’s end of life.

With the wick off-center due to wick migration, the candle will begin to burn unevenly and form soot on the side of the container’s wall where the flame is too close. It may not sound dangerous, but it is to the brand’s reputation and the candle’s safety. End-users may not purchase your candle brand again since their overall experience was compromised by wick migration. While an uneven burn, sooting, and the candle’s flame too close to the container’s wall caused by wick migration do not sound dangerous, it is indeed.

The flame near the container’s wall often causes localized overheating of the container and the liquid wax pool. As a result of localized overheating caused by wick migration, the candle’s container could get too hot and transfer heat to adjacent surfaces and even crack, causing the wax to flow out of the container and causing a fire hazard. To mitigate the chance of wick migration it is vital to use the appropriate heat resistant candle glue.

Candle manufacturers and fillers depend on RT2315 to improve production line efficiency for several reasons. First, RT2315 glue deposits are precise and repeatable, making them ideal for high-speed production lines when the machinery is at their optimal operating temperatures. Second, RT2315 features a short open time, the specific amount of time to bond the materials (wick clip assemblies and the container) together before the adhesive starts to form a skin. The short open time enables manufacturers and fillers to begin instantaneous wax filling, saving them precious time. Third, unlike other hot melt candle adhesives, RT2315 deposits are clean without the stringing associated with other glues not designed for candle applications, keeping the production area and machinery nozzles clean.

Now that you have a basic understanding of RT2315 adhesive let’s explore some common questions from our customers.

Common Questions About RT2315 Hot Melt Candle Glue

Question: Can RT2315 glue secure wick clip assemblies in all types of candles?

Answer: Yes, RT2315 can be used to secure wick clip assemblies in many different candle types, including paraffin, soy, beeswax, and other waxes or blends. As with everything in candle manufacturing, it is always important to refer back to the wax manufacturer’s instructions to ensure adhesive compatibility.

Question: Will RT2315 work with Wicks Unlimited’s tin-coated wick clip assemblies and sustainers?

Answer: After extensive research and testing, the combustion experts at Wicks Unlimited selected to stock RT2315 because of its excellent surface adhesion to tin-coated wick clip assemblies at high temperatures.

Question: My current adhesive fails during pouring and towards the candle’s end of life, causing wick migration. Will RT2315 prevent wick migration?

Answer: RT2315 dramatically reduces the chances of wick migration since it has been successfully tested to withstand high temperatures while still providing superior wick clip assembly anchoring.

Question: What is the melting point of RT2315?

Answer: The melting point is approximately 320℉.

Question: What is the softening point of RT2315?

Answer: The softening point is 290℉.

Question: Does RT2315 experience “stringing” like other hot melt glues?

Answer: RT2315 does not experience “stringing” like other hot melt glue due to its molecular structure.

Question: How is RT2315 deposited into a candle’s container?

Answer: The most effective method to deposit RT2315 into empty candle containers or molds is using industrial glue depositing machinery at the optimal operating temperature featuring zero cavity nozzles for quick adhesion. Please contact Wicks Unlimited to learn more about how to deposit RT2315 into containers and molds.

Question: What type of candle containers is RT2315 compatible with?

Answer: RT2315 candle adhesive is compatible with many different substrate types including both glass and metal containers.

Question: My customers like repurposing the candle’s container after the final burn cycle. Is RT2315 easy to remove?

Answer: Many other types of glue are too gooey to remove entirely from the bottom of the candle’s container. However, RT2315 is easy to remove from the bottom of the container, making repurposing a breeze.

Question: What is the minimum order quantity (MOQ) for RT2315?

Answer: RT2315 glue pillows are available in bulk packaging starting at quantities as low as 50 pounds.

Question: How can I view a Safety Data Sheet (SDS)?
