What is hot melt adhesive S-395? How to choose high-end low-temperature resistant graphic and text store adhesive (benchmarking against Henkel 3218)

In graphic and text fast printing stores, the choice of glue is often stuck between “mid-range enough” and “high-end durable”. In Sunlife’s graphic and text store hot melt adhesive,S-393 pairs well and is a key player in the mid-rangeBut S-395 benchmarking against Henkel 3218, pursuing high-end low-temperature resistanceIf your store often encounters brittle and low-temperature peeling in winter, or if customers have high requirements for the texture of finished products, S-395 is prepared for such scenarios. Now let’s explain what S-395 is, what are the differences between S-393, and how to choose it.

1、 The position of S-395 in the glue of Sunlife graphic store

Sunlife graphic store hot melt adhesive is divided into two lines according to the level:

Background: About half of the hot melt adhesives used in domestic graphic and text stores are from HeDe Miao, ranking first, while Sunlife graphic and text store adhesives overall rank second in the country. S-393 and S-395 are the high and low combinations of Sunlife on this track.

2、 The core problem solved by S-395: low-temperature embrittlement

One of the most headache inducing scenarios for graphic stores isWinter or low-temperature workshop——Ordinary glue becomes hard in low temperature environments, the spine becomes brittle, and pages fall off during transportation. As a high-end model with low temperature resistance, S-395 is designed to maintain toughness even at low temperatures and is suitable for:

• Picture and text stores in northern winter without heating or low-temperature warehouses;
• Orders for finished products to be shipped to low-temperature areas;
• Albums, bidding documents, and hardcover materials that require flexible spine and high tactile requirements for flipping through.

3、 How to choose S-395 and S-393

• Daily quick printing of graphics and text, large quantity with low profit margin → Choose S-393, a mid-range mainstay with high cost-effectiveness;
• Low temperature environment/High quality requirements/Alternative to the benchmark Henkel 3218 → Choose S-395, which has good low temperature resistance and toughness;
• Both are used within the melt adhesive window of 160-180 ℃ (precise process parameters are subject to the accompanying process card). When changing models, remember to clean the glue tank and not mix different models.

4、 On site landing suggestions

Tell Sunlife about whether there are any pages missing in winter, where to send the finished products, and customers’ requirements for texture. The technology will follow the instructionsMachine speed+paper+ambient temperatureProvide clear recommendations for S-393 or S-395 and attach a process card. Don’t just choose “cheap”, the cost of rework for low-temperature peeling is often more expensive than the glue itself.

Frequently Asked Questions

Can S-395 completely replace S-393?

It can stick, but it’s not necessary. S-395 is positioned as a high-end low-temperature resistant product with higher unit price and performance; S-393 is more cost-effective for regular graphics and text at room temperature, while S-395 is only suitable for low temperature/high demand scenarios.

Do I need to change the equipment when switching to S-395?

No need to change the equipment, just use the same glue installation machine and the same glue window (160-180 ℃); The key is to clean the adhesive groove when changing the type and not mix it with old adhesive.

The S-395 is not the “more expensive S-393”, but a model specifically designed to address the weakness of “low-temperature embrittlement” in Sunlife’s graphic store adhesive. Clearly state the environmental temperature and quality requirements, and Sunlife matches the model and process card according to the purpose, which is much more stable than guessing the gear by oneself.
