High Performance Water based Die Release Agent RLT-9640

RLT-9640 is a premium water-based Die Casting Release Agent engineered for aluminium, magnesium, and zinc high-pressure die casting applications. This stable aqueous emulsion is formulated for conventional spray, reduced spray, and low-volume micro-spraying systems, making it one of the most versatile release agents available for modern die casting operations.

The product is manufactured using computer-controlled fully automated emulsification and feeding production lines, with electronic quantitative filling ensuring batch-to-batch consistency. Every batch is produced with deionized secondary reverse osmosis purified water, resulting in uniform molecular diameter and exceptional resistance to carbon deposition.

With a recommended dilution ratio of 1:400–450 with tap water, RLT-9640 delivers outstanding cost-efficiency while maintaining superior release performance across a wide range of casting applications.

Properties And Advantages

● Castings are well suitable for joining processes like welding and glueing

● Excellent paintability and powder coating ability of castings

● Tried and tested on conventional, reduced, as well as micro-spraying

● Good die release and good lubrication of ejector pins

● Effective  reduction  of  "metallization"  (metal-on-metal  welding) ,excellent  and shiny surfaces of castings

● High process reliability (stable emulsion, no separation, no stirring required) ,clean die frame and environment;no clogging  of pipes and spray nozzles

Application

Suitable for a wide spectrum of castings, also for large structural and heavy parts.Die temperatures:from about 130 to 350 °C.

The ultimate or ideal dilution ratio for a particular casting is determined by: duration of spray, spray velocity, geometry and complexity of casting as well as the temperature of the tooling. On-site tests should therefore be carried out to establish the correct ratio for each particular application.

Recommended dilution ratios with tap water

Product         Aluminium and Magnesium

RLT-9600:            1 : 100-120

RLT-9630:            1 : 250-300

RLT-9640:            1 : 400-450

RLT-9640 is available in several concentrations, each of them will dissolve in water instantly. Prior to use,RLT-9640 must be diluted with water. Thereafter the diluted product should not be stirred in order to prevent foaming. Do not use air agitation. Immediately after use, the containers with the release agent concentrate must be closed tightly.

Chemical And Physical Data

Why Choose RLT-9640?

1. Unmatched Cost Efficiency

With a dilution ratio of 1:400–450, RLT-9640 significantly reduces your per-part release agent costs compared to conventional 

products with lower dilution capabilities.

2. Superior Casting Quality

Castings produced with RLT-9640 are clean, bright, and exhibit excellent surface finish. The effective reduction of "metallization" 

(metal-on-metal welding) ensures shiny, defect-free surfaces.

3. Post-Processing Ready

Parts released with RLT-9640 are readily paintable, powder coatable, weldable, and gluable—eliminating the need for costly 

post-casting cleaning operations.

4. Process Reliability

The stable emulsion formula requires no stirring and exhibits no separation, even after extended use. Spray systems remain 

clean and clog-free, reducing maintenance downtime.

5. Full Production Traceability

Every batch is produced under strict quality control with full traceability from raw materials to finished product. Each drum 

can be traced back to specific raw material batch numbers and production parameters.

6. Environmentally Responsible

As a water-based formulation, RLT-9640 offers a safer, more environmentally friendly alternative to solvent-based release 

agents.
