Technical Data Sheet

Flocklok

852 is a single-coat surface treatment used

to affix polyester or nylon flock fibers to a variety of

elastomers. Flocked substrates provide good resistance to

abrasion. Flocklok 852 will react and cure with moisture;

however, an elevated temperature cure is required to

optimize performance properties.

Mixing – Mix Flocklok 852 for 30 minutes with drum

mixer at low speed to disperse any settling that may

have occurred during storage. Then mix for a minimum

of 4-6 hours at 40-60 rpm using the agitator contained in

an agitator drum or other suitable mixer. Maintain either

continuous mixing at 15-30 rpm or mix the drum for 10

minutes every hour at 15-30 rpm.

If application method requires dilution, use xylene as the

diluent.

The cure rate of Flocklok 852 is improved by using Flocklok

Catalyst 9986. Adding 1-4% catalyst is suggested. A pot

life of 1-2 days can be expected when stored at 21°C

(70°F) and material is protected from moisture.

Applying – Transfer Flocklok 852 using a peristaltic pump

or pressurized vessel.

Apply Flocklok 852 at a wet film thickness of 101-152

micron (4-6 mil), which is the dry film equivalent of 51-76

micron (2-3 mil). Thicker films of Flocklok 852 may be

required depending upon profile temperature and flocking

efficiency.

The optimum profile temperature at time of application

is 52-79°C (125-175°F). Optimum appearance after

application is a uniform brown color with no black profile

color showing through, no streaks and no “fisheyes”.

Curing – An elevated temperature cure cycle is required to

optimize performance to EPDM elastomers. The cure cycle

is time and temperature dependent. Cure temperatures

usually range from 190-232°C (375-450°F). A typical cure

cycle is 3 minutes at 204°C (400°F) or 2 minutes at 232°C

(450°F) in a forced, hot air oven. On exiting the curing oven,

a flocked profile surface temperature of 162-190°C (325-

375°F) is optimal for cure and performance properties.

Features and Benefits:

Versatile – performs under a wide range of cure

conditions.

Excellent Performance – provides excellent performance

on a wide variety of elastomers and types of flock.

Process Compatible – may be used on-line or off-line;

can be catalyzed to achieve faster set time.

Elastomers:

• Styrene-butadiene (SBR)

• Polychloroprene (CR)

• Nitrile (NBR)

• EPDM Polymers

Application:

Surface Preparation – Remove contaminants (e.g.,

dirt, rubber bloom, processing oils and mold release)

from substrate surface. For some rubber compounds,

performance is enhanced by using surface treatments such

as corona, plasma or mechanical abrasion.

Flocklok 852 — Technical Data Sheet

Cleanup – Purge fluid lines and equipment with ketone or

aromatic solvents. Do not use water. Once Flocklok 852 is

in a dried and cured state, clean up will not be possible.

Shelf Life/Storage:

Shelf life is one year from date of manufacture when stored

in a well ventilated area at 21-27°C (70-80°F) in original,

unopened container. If not stored at ambient temperature,

equilibrate container at ambient temperature for 48 hours

prior to initial mixing and use. Do not store or use near

heat, sparks or open flame. Store container out of direct

sunlight.

Flocklok 852 is moisture sensitive. Minimize exposure to

moisture during application and storage.

技术说明书

Flocklok

852是一种单涂型表面处理剂， 用于帮助和促进

聚酯或尼龙植绒纤维附着至各种弹性体上。植绒基材具有良

好的耐磨性。Flocklok 852会与湿气反应并固化；为了提供与

基材最佳的附着力，还需进行高温固化。

混合 – 大桶中用机械搅拌器低速混合Flocklok 852 30分钟，

以分散储存过程中可能出现的任何沉淀物。 然后使用包装

桶自带的搅拌器或其他合适的搅拌器以 40-60 rpm 的转速

至少搅拌 4-6 小时。使用时，保持15-30 rpm的转速持续搅

拌，或以15-30 rpm的转速每小时搅拌10分钟。

如果需要稀释，请使用二甲苯作为稀释剂。

加入Flocklok Catalyst 9986催化剂， Flocklok 852的固化速

度会加快。建议添加 1-4% 的催化剂。在 21°C (70°F) 及没有

湿气的条件下，加入催化剂的产品适用期为 1-2 天。

涂敷 – 使用蠕动泵或压力容器输送Flocklok 852。

按照101-152 微米（4-6密耳）的湿膜膜厚涂敷Flocklok 852，

相当于51-76微米（2-3 密耳）的干膜。根据型材温度和植绒

效率，可能需要更厚的Flocklok 852膜层。

涂敷时的最佳型材温度为52-79°C（125-175°F） 。涂敷后的

最佳外观是均匀的棕色，看不到黑色型材，无条纹和“鱼眼”。

固化 – 需要高温固化来提升对EPDM的附着力。 固化周

期取决于时间和温度。固化温度的范围通常在190-232°C

(375-450°F)。典型的固化周期为 204°C (400°F) 时 3 分钟，

或 232°C (450°F) 时 2 分钟（使用热空气烘道）。 离开固化烘

箱时，植绒型材表面的温度介于162-190°C (325-375°F)时

是确保固化和性能的最佳温度。

清理 – 使用酮类或芳烃熔剂清理液体管路和设备。请勿使

用水。一旦Flocklok 852处于干燥和固化状态，则无法清理。

特征和优点:

弹性体:

多功能性 – 可在广泛的固化条件下发挥功用。

性能优异 – 适用于多种弹性体和植绒。

工艺兼容性 – 在线或离线均可使用；加入催化剂可实现快

速固化。

• 丁苯橡胶 (SBR)

• 氯丁橡胶 (CR)

• 丁腈橡胶 (NBR)

• EPDM 聚合物

使用方法:

表面处理 – 从基材表面除去污染物（例如灰尘、橡胶喷霜、

操作油和脱模剂）。 针对某些橡胶混合物，可以使用电晕、等

离子处理或机械打磨以提升性能。
