The Ultimate Guide to GR-3012 Wet Strength Agent (PAE Resin)

In the competitive papermaking industry, ensuring that products maintain their integrity when exposed to moisture is a top priority. Whether you are manufacturing household tissues, industrial packaging, or specialty papers, the quality of your wet strength agent directly impacts your brand reputation and production costs.

Today, we take an in-depth look at GR-3012, a high-efficiency PAE resin from Guanru Chem designed to revolutionize paper strength performance.

What is GR-3012 Wet Strength Agent?

GR-3012 is a high-performance polyamide epichlorohydrin (PAE) resin specifically developed for the papermaking industry. As a thermosetting resin, it creates a robust chemical network within the paper fibers, ensuring that the paper retains significant strength even when fully saturated with water.

Unlike traditional additives, GR-3012 is engineered as a versatile solution in the Papermaking Additives category, offering superior retention and stability across various production environments.

Key Benefits of Using GR-3012 in Your Mill

Why are leading paper mills switching to GR-3012? Here are the technical and economic advantages:

1. High Efficiency & Cost Reduction

GR-3012 features a high solid content and superior fiber affinity. This means you can achieve the desired wet-to-dry strength ratio with lower dosages, directly reducing your chemical procurement costs.

2. Wide pH Range Adaptability

One of the standout features of GR-3012 is its ability to perform across a wide pH spectrum (neutral to alkaline). This flexibility allows it to be used with various pulp types, including recycled fibers and virgin wood pulp, without losing efficacy.

3. Environmentally Friendly Compliance

As global regulations tighten, Guanru Chem has optimized the GR-3012 formula to ensure low levels of organic chlorine residues (DCP/MCPD). This makes it safe for food-contact paper and eco-conscious consumer products.

Common Applications for GR-3012

Our GR-3012 Wet Strength Agent is the preferred choice for a variety of high-demand paper grades:

• Household & Sanitary Paper: Facial tissues, paper towels, and napkins that must remain functional when wet.

• Packaging Solutions: Liquid packaging boards, frozen food containers, and heavy-duty carrier bags.

• Specialty Papers: Outdoor posters, maps, labels, and currency paper that require extreme environmental resistance.

Technical Application & Dosage Recommendations

To achieve the best results with GR-3012, it is typically added at the thick stock stage or after the fan pump.

Recommended Dosage: 5kg to 30kg per ton of absolute dry fiber (depending on specific strength requirements).

Optimization Tip: For maximum cross-linking efficiency, maintain a system pH between 6.0 and 9.0.

By integrating GR-3012 into your production line, you can reduce paper breakage on the machine, increase production speed, and deliver a superior final product to your customers.
